Don't trust map my run

Did my first park run today think I started too fast as I had to walk most of the second lap having said that I managed a time of 37.38 not to shabby. However map my run said I'd only run 4.5km so god knows how long I run for the other day when I thought I'd done 5k. Shall be going again next week really enjoyed the atmosphere.

Hey, we've had a couple of posts today about tech not being accurate. Futbut, map my run and others too. I reckon you just have to take them with a big pinch of salt and use them for understanding your relative gains. I thought parkruns were all calibrated exactly, so take the gain and we'll done for going out

I trust there measuring more than my phone I'd done what I thought was a 5k the other day but it must have been further than I thought.

Parkruns are all measured distance and should be pretty close to 5k.

Do you run through trees? Anything blocking the signal can give a duff result. It is more likely your phone than the app, that is guilty.

Glad you enjoyed parkrun. It is brilliant.

There is a bit of the trail that goes through the woods so that could explain it. I trust there measuring more than my phone I'd done a run the other day on the road that I thought was 5k but must have been longer as it took me longer and I ran the whole way.

A dedicated gps sports watch is generally more accurate than a phone

I keep looking but there's that many out there I'm unsure which one to get. I don't want to spend loads of money on something that's going to be rubbish.

That was easy, wasn't it?

Well, the phones rubbish at recording accurately, the Garmins aren't rubbish, I have one and the wife uses a basic FR10 as a lot do on here, so there's a good review.

I have two Garmins, I was lucky enough to be gifted one. One of them is much better than the other at all sorts of thing, like run/walk intervals, but it loses the signal under trees, and on cloudy days more often than the other. So - I often wear both. I can tell you that they nearly always have a difference in distance. I've come to realise these things are really a bit hit and miss a lot of the time, if you do the same route often you will regularly find differences. I never take the info I get from either of them as gospel.

If you walked most of a lap, 4.5k in 37 minutes sounds pretty reasonable tbh. You'd have had to be tonking the first lap to hit 5k. I'd have thought

The first part of the first lap was down hill and with all the other runners I think I must of and would explain why I was dead on the second lap
